Together they make up what we now call the vitamin B complex (the same as the original “factor B”).

We also now know that our bodies use each B vitamin for distinct purposes.

Adding to the confusion, not all of the vitamins classified as B vitamins are actually vitamins.

There are now only eight “true” B vitamins, but the list used to be longer.

For instance, vitamin B4, 8, 10, and 11 are no longer considered vitamins.

B vitamins are water soluble vitamins that play an essential role in metabolism.

Because they are water soluble, they don’t build up in the body, so if you get too much, you will only get jittery or nauseous.

While vitamins are available through food, many take supplements to ensure they are getting the optimal amount.

The B Vitamins

Vitamin B1

Also known as thiamin, vitamin B1 helps convert food into energy, plays a role in muscle contractions, and supports proper nervous system functions. Additionally, it is often called the “anti-stress” vitamin because of its ability to protect the immune system.

Vitamin B3

Also known as niacin or niacinamide, vitamin B3 helps the digestive system, skin, and nerve function. In addition, it supports cellular energy production and boosts HDL cholesterol (the good cholesterol).

Vitamin B5

Also known as pantothenic acid, vitamin B5 is needed for our bodies to break down fats and carbohydrates for energy. In addition, B5 is necessary for our bodies to produce hormones, as well as needed for growth.

B5 is found in:

just about every food group – the name even says so. Pantothenic comes from the Greek word “pantothen,” meaning “from everywhere.”
